Example

using Leadtools; 
using Leadtools.Controls; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
using LeadtoolsExamples.Common; 
 
public void RasterPictureBox_AnimationModeChanged() 
{ 
   RasterPictureBox viewer = new RasterPictureBox(); 
   viewer.PropertyChanged += viewer_PropertyChanged; 
 
   switch (viewer.AnimationMode) 
   { 
      case RasterPictureBoxAnimationMode.Infinite: 
         viewer.AnimationMode = RasterPictureBoxAnimationMode.UseImageGlobalLoop; 
         break; 
 
      case RasterPictureBoxAnimationMode.UseImageGlobalLoop: 
         viewer.AnimationMode = RasterPictureBoxAnimationMode.Infinite; 
         break; 
   } 
 
   viewer.PlayAnimation(); 
   viewer.PropertyChanged -= viewer_PropertyChanged; 
} 
 
private void viewer_PropertyChanged(object sender, PropertyChangedEventArgs e) 
{ 
   if (e.PropertyName == "AnimationMode")

      RasterPictureBox viewer = sender as RasterPictureBox; 
      string s = string.Format("AnimationModeChanged Event: {0}", viewer.AnimationMode.ToString()); 
      MessageBox.Show(s);
